Excellent germination rate
For easiest germination I placed 10 seeds in a small dish of water, covered the top with plastic wrap and placed the dish on top of the refrigerator. By day 3, 7 of the seeds had sprouted and by day 5 all 10 seeds had germinated. Each "sprout" was then placed into moist potting soil and placed under grow lights. They are all about 5" tall at the moment and am looking forward to seeing how they "grow on" when transplanted in the garden next month. VERY pleased with this seed.

80% Germination rate in water
While most perennial milkweed seed must be cold stratified, we've had excellent success with Asclepias tuberosa (aka Butterfly Weed) by simply placing seed in a shallow dish of water, covering with plastic wrap and putting the dish in a warm place (on top of the refrigerator). Seeds sprout in a matter of days and are then placed into moist soil to grow on under lights or in a sunny window. Of the 10 "Hello Yellow" seeds placed in a dish 3 days ago, 8 have sprouted. 80% germination rate is fairly standard for milkweed seed so we are happy with the results.
